Antunovi said the Semi's technology, particularly regenerative braking, has also been a great help for Pepsi, especially on the challenging routes that include the Donner Pass. "Going across Donner Pass and back from [Sacramento] to Nevada, we're able to, on the trip back, actually zero out, in terms of state of charge improving due to regenerative braking… It extends range for us in a way that is invaluable," Antunovi said.

It seems kind of ludicrous to make a statement like this. It's easy to "zero out" your energy usage when you're going downhill. If Fred Flintstone rolled his car down Donner Pass, he could make his way all the way to the bottom without expending a single calorie providing motive power to the car with his feet.

Obviously you did not understand the statement! The actually GAIN energy going downhill compensating for the energy required to go uphill!
